Hi!
I am a newbie trying to compile the program JACK that is required for
the midi sequencer Rosegarden. This program (JACK) is not available
through the ports collection and is intended for a Linux system. I am
running FreeBSD 5.4 with linux compatibility supported. Below is is the
readme file for JACK and I have chosen to follow the second option. I
have created the /mnt/ramfs directory and edited my /etc/stab file as
directed. What I don't understand is the last instruction of the second
option listed below, the line that says,
"add --with-default-tmpdir=/mnt/ramfs to the JACK configure line when
you build it".
I tried "make --with-default-tmpdir=/mnt/ramfs" and received a message
informing me that this is not correct Make syntax.
Am I supposed to edit the config file(s) that accompany the source
code? If so, which one(s), config.h.in, configure, configure.ac or one
of the files in the config directory of this package?
This is probably a very simple matter, but I have googled around and
cannot find an answer. Any comments, suggestions or advice would be
greatly appreciated.
Thanks,
Lawrence
JACK README
Welcome to JACK, the Jack Audio Connection Kit.
Please see the website (http://jackit.sf.net/) for more information.
NOTE: If you are using reiserfs or ext3fs or anything except ext2fs
for the directory where JACK puts its temporary files (/tmp by
default), then the JACK team recommends that you do *one* of the
following:
----------------------------
Mount a tmpfs on /tmp. You should have a lot of swap space available
in case some programs try to write very large files there.
In your /etc/fstab add a line:
none /tmp tmpfs defaults 0 0
You'll probably want to reboot here, or kill X then 'mount /tmp'.
---- OR ----
Alternatively, you can do this without affecting your /tmp:
# mkdir /mnt/ramfs
[edit /etc/fstab and add the following line]
none /mnt/ramfs tmpfs defaults 0 0
Then add --with-default-tmpdir=/mnt/ramfs to the JACK configure
line when you build it. No clients need to be recompiled.
------------------------------
Failure to do one of these could lead to extremely poor performance from
JACK,
since its normal operation will cause bursts of disk I/O that are
completely unnecessary. This suggestion can also be used by ext2fs
users if they wish.
